The Geneva-based laboratory for particle physics has released a vast archive of photographs dating back to the mid-1950s. The problem is that many of them have no captions – so scientists at Cern are asking the public for help

Cern has made 120,000 photos, covering the years 1955-85, searchable online. “We believe that much of this information could be crowd-sourced from the Cern community,” says a blog on the lab’s website. If you recognise an object or, better still, one of the people, email
photo.archive@cern.ch and take your own tiny place in scientific history.
